DFS4750W USING IRLM IS RECOMMENDED FOR DIRECTORY CLEANUP
Explanation
IRLM was not used when the batch recovery utility was running to clean up the directory. IRLM is used to serialize the update of the directory data set between the online and batch processing.
System action
The batch recovery utility continues the directory cleanup.
Programmer response
Ensure that the batch recovery utility is running only when the IMPORT DEFN SOURCE(CATALOG) command and the DDL definition activation are not running at the same time. Issue IMPORT MEMBER TYPE(IMS) SHOW(ALL) to determine whether an import processing is in progress.
